4 1. EXECUTIVE SUMMARY The National Energy Regulator (NERSA) is the regulatory authority over the energy sector in South Africa and its mandate includes the regulation of the electricity supply industry. In terms of section 4(ii) of the Electricity Regulation Act, 2006 (Act No. 4 of 2006) ( the ERA ), the Energy Regulator must regulate electricity prices and tariffs. The Energy Regulator approves a percentage guideline increase and reviews the municipal tariff benchmarks, on an annual basis. The guideline increase assists the municipalities in the preparation of their budgets and tariff adjustment applications. On 23 February 2017, the Energy Regulator confirmed a determination on the final year (2017/18) of Eskom s third Multi-Year Price Determination (MYPD3) period. Subsequently, Eskom s Retail Tariff Structural Adjustments (ERTSA) application was approved. The municipal tariff guideline increase is developed based on Eskom s approved bulk price increase of electricity to municipalities and the increase on the municipalities cost structures. Hence the approval of the municipal guideline increase is subsequent to the determination of ERTSA. The benchmarks are developed in order to ensure that tariffs across municipalities are not vastly different and are used in the evaluation of the municipal tariff applications. This consultation paper on the guideline is issued in line with the MYPD decision as approved by the Energy Regulator and confirmed on 23 February In the instance that circumstances change the current decision of the Energy Regulator which has influenced the development of this guideline, in line with the provisions of the ERA, NERSA will ensure that licensees are able to recover the full cost of licensed activities through an adjustment mechanism that NERSA will consider necessary. The Energy Regulator is requesting the stakeholders to comment on the percentage guideline increase, the benchmarks and the proposed timelines as set out in this consultation paper. The comments should be addressed to: Ms Tabisa Nkopo or Ms Nthabiseng Mapitsing at The National Energy Regulator, Kulawula House, 526 Madiba Street, Arcadia, Page 3

5 Pretoria or ed to: The deadline for the submission of comments is 20 March NERSA will not hold a public hearing on the key issues highlighted in the consultation paper, but will follow the notice and comment procedure in terms of Section 4 (3) of the Promotion to Administration Justice Act, 2000 (Act No. 3 of 2000). This is due to the fact that in the past, few to no presenters attended the public hearing to make representations to NERSA. 2. BACKGROUND The consultation paper incorporates price or tariff adjustments by municipal distributors, the municipal tariff benchmarks, tariff applications and the approval processes. Eskom generates approximately 95% of the energy that is consumed in the country and the municipal distributors purchase their energy from Eskom. All municipalities are informed about the approved guideline percentage increase. This is not an automatic increase for the municipalities and private distributors. As a result, NERSA allows licensees to submit their proposed price adjustments or tariff increases annually for approval by the Energy Regulator. Benchmarks are based on five tariff categories and the corresponding average consumption levels. NERSA acknowledges that these are average consumption levels and that there may also be other tariff classes at various municipalities that will cater for other customer classes or consumption levels. Where such circumstances exist, the municipality s tariff applications will be treated on a case-by-case basis. According to the NERSA timelines, the municipal tariff guideline and benchmarks will be approved in April Municipalities are required to submit their tariff applications to NERSA as soon as possible upon receipt of the municipal tariff guideline letter.

Issues considered in the analysis of the municipal tariff review NERSA approved a Cost of Supply (COS) study framework as it is a requirement of the Electricity Pricing Policy (EPP). Therefore, municipalities are urged to perform cost of supply studies so that the revenue earned by the municipalities per tariff category is aligned with the cost to supply electricity. The following factors, among others, will be taken into account when determining the average cost to supply: a) bulk purchases; b) bad debts; c) reasonable energy losses; d) direct and indirect charges; e) salaries and wages; and f) capital charges. Page 5

7 The municipalities overall financial and technical performance will be reviewed prior to a final decision on the overall tariff increase. Indicators to be considered in this regard mainly include: a) percentage surplus; b) percentage energy losses; c) percentage power costs; d) repairs and maintenance; e) bad debt provision; and f) average selling price/average purchase price ratio Submission of D-form information NERSA held workshops and one-on-one interactions with municipalities per province in order to assist municipalities with the completion of the Distribution forms (D-forms). This process ran parallel with the submission of the D-forms. Access to the D-form templates can be obtained through the NERSA website ( The closing date for the submission of the D-forms is 31 October annually. Municipalities that have been contacted by NERSA regarding inaccurate or outstanding data are required to ensure that accurate information is submitted timeously to NERSA, in order to ensure that proper analysis is done and the approval of the tariff applications is achieved. The distribution forms that are primarily used for the tariff approval process are D1 (Financial information), D2 (Market information) and D3 (Human Resources information). These forms contain information regarding the financial position, efficiency levels of the municipality, data regarding the customer s consumption patterns and the number of customers per tariff category. This information assists NERSA in the analysis of the tariffs and in determining the revenues that the municipality collects from the various tariff categories. NERSA will not consider any municipal tariff applications without the submission of appropriate and accurate D-form information. Page 6

8 3. DETERMINATION OF THE MUNICIPAL TARIFF GUIDELINE When developing the percentage guideline increase for 2017/18, the following issues were considered and the assumptions were made. On 23 February 2017, the Energy Regulator granted Eskom an annual average increase of 2.2% leading to a bulk purchase increase of 0.31% for municipalities. This is due to the Municipal Finance Management Act, 2003 (Act No. 56 of 2003) ( the MFMA ) time lag (the municipalities' implementation date is 01 July whereas Eskom's financial year starts on 01 April). Issues considered when developing the percentage guideline increase for 2017/18: a) The 2014/15 D-form information was used to determine whether there would be changes to the municipality s cost structures. b) A stratified random sampling amounting to 140 D-forms was done. c) The chosen sample is useful in determining whether the weights of the cost drivers that have been developed need to be revised or maintained. The pie chart below indicates the findings from the analysis done from the various sized municipalities. 2016/17 AVERAGE COST STRUCTURE 2017/18 AVERAGE COST STRUCTURE 6% 3% 6% 10% 75% % Purchases %Salaries & Wages % Repairs % Capital Charges % Other Costs 10% 6% 4%5% 75% Page 7

9 The data from the computed various sized municipalities indicated a change in the weights of the cost structures. The municipal bulk purchases remain unchanged at 75% as the increase in bulk purchase was insignificant. The average percentage for salaries and wages has been maintained at 10% in order for municipalities to incorporate the recruitment of skilled staff, additional staff and the allowance for paying scarce skills allowance. NERSA requires municipalities to spend 6% of their total ring-fenced electricity revenue on repairs and maintenance to ensure a sustainable electricity supply system. The capital charges increased from 3% to 4% and other costs have been reduced from 6% to 5% in order for municipality to allocate their costs accordingly. Municipalities must submit their specific cost drivers should they be different from the ones presented by NERSA in the consultation paper. This will assist NERSA in considering municipalities on a case-by-case basis based on their actual cost structures. Stakeholder Comment # 1 Stakeholders are invited to comment on the changes in the breakdown of the cost weighting that NERSA has taken into consideration when developing the guideline. In developing the guideline, the following assumptions on cost increases were made: a) Bulk purchases will increase by 0.31% as indicated in the Eskom standard tariff submission for the 2017/18 financial year. b) Consumer Price Index (CPI) 6.2% 1. c) Salary increase CPI plus 1% 2. d) Repairs and maintenance, capital charges and other costs will increase by CPI. 1 As indicated in the Bureau for Economic Research (BER) 2017/18 2 As indicated in Circular No. 31/2015: Salary and Wage Collective Agreement Page 8

10 3.1. The formula for calculating the guideline increase: MG = (BP x BPI) + (S x SI) + (R x RI) + (CC x CCI) + (OC x OCI) = (75 x ) + (10 x 0.072) + (6 x 0.062) + (4 x 0.062) + (5 3 x 0.062) = = 1.88% Where: MG = % Municipal Guideline Increase BP = % Bulk purchases BPI =% Bulk purchase increase S = % Salary SI = % Salary increase R = % Repairs RI = % Repairs increase C = % Capital charges CCI = % Capital charges increase OC = % Other costs OCI= % Other costs increase Table 3: Calculation of the guideline for the 2017/18 financial year REVISED MUNIC % OF TOTAL COST EXPECTED INCREASE % WEIGHTED AVERAGE EXPECTED INCREASE % COST LINE ITEM Purchases Salaries and wages Repairs & Maintenance Capital charges in total Other Costs % increase 1.88 Municipalities applying for an increase that is above the guideline will have to justify their increases to the Energy Regulator and the approval will be based on the following requirements: 3 The other costs have been reduced in order for municipalities to allocate their costs accordingly. 4 Charges allocated from and to municipal departments, general expenses (costs related to the Municipal Electricity Department but not indicated on the D-forms). Page 9

11 a) a detailed plan on the additional funds requested needs to be presented to NERSA as part of the motivation for the above-guideline increase (the municipality must provide a detailed revenue analysis whereby it indicates the revenue when using the approved guideline percentage increase versus the actual required revenue and the list of items, i.e. repairs and maintenance, where the extra funds will be allocated); b) the approved funds must be ring-fenced to ensure that the extra funds are strictly utilised for the identified projects; c) municipalities must report to NERSA on a six-monthly basis on how the additional funds are utilised; and d) funds not utilised for the purpose for which they were approved will be clawed back in the following financial year. 4.

Stakeholder Comment # 2 Stakeholders are invited to comment on whether NERSA should consider other indicators when determining the efficiency of the municipality. 6. MUNICIPAL TARIFFS ABOVE THE NERSA BENCHMARKS Municipalities applying for tariffs that are outside the approved benchmarks must justify such increases and the following information must be submitted: the total number of customers per tariff category municipalities that do not have an appropriate customer base must submit the full detail of its customer profile, as well as the associated revenues; expected revenues per tariff category; the forecasted total sales; 5 The acceptable ranges are NERSA s allowable ranges. 6 In accordance with the municipal cost structure as indicated in the municipal tariff guideline consultation paper. 7 The applicable financial benchmark for municipalities. 8 The applicable technical benchmark for municipalities.

18 the average maximum demand per tariff (where applicable); the actual consumption; and the load profile in percentages (both summer and winter, where applicable). The municipalities are encouraged to develop time-of-use tariffs in order to enable the customer to benefit from shifting their load. This will also enable municipalities to charge their customers prices that are similar to what Eskom is charging them. 7. THE PROPOSED MUNICIPAL ELECTRICITY TARIFF BENCHMARKS FOR 2017/ The revised benchmarks The benchmarks for the 2017/18 financial year have been developed as follows for the different tariff categories Domestic Benchmarks (Block 1 4) The domestic tariffs for the 2016/17 benchmark were increased by the municipal tariff guideline increase of 1.88%.

TIMELINES FOR MUNICIPAL TARIFF APPROVAL PROCESS AND GUIDELINE DETERMINATION Municipalities are bound by among other legislation, the MFMA and Municipal Systems Act (MSA). According to the MFMA budgetary process, a budget circular to all municipalities is issued by National Treasury by the end of November annually. This circular takes into account NERSA s approved guideline increase. It is anticipated that municipalities will compile and submit tariff applications for NERSA s consideration from April Section 43 of the MFMA states that: (1) If a national or provincial organ of state in terms of a power contained in any national or provincial legislation determines the upper limits of a municipal tax or tariff, such determination takes effect for municipalities on a date specified in the determination. (2) Unless the Minister on good grounds approves otherwise, the date specified in a determination referred to in subsection (1) may - a) If the determination was promulgated on or before 15 March in a year, not be a date before 1 July in that year; or b) If the determination was promulgated after the 15 March in a year, not be a date before 1 July in the next year.
